Isn't there an outside chance that a big glob of material ejected from a black hole could be going 99.999999% relative to earth, and impact hard enough to break the planet up?
Little bit of a bump, but I was reading about kinetic energy impactors on Wikipedia:
I always thought Tungsten had very low shatter resistance, but this claims Tungsten as being superior for surviving high speed impacts than equivalent high quality steel.
Is it possible to do something similar to making diamonds in which a material is compressed until it transitions to a stable new crystal configuration instead of "bouncing back"?
I was thinking that since the density of something is as much dependent on the molecular structure as the atomic, that there should be some leeway here.
I mean brittle in the scientific sense, but also that the material doesn't easily fracture, which is the more colloquial, non-scientific sense of "brittle".
So, I'm looking for the hardest (most difficult to pierce/cut) material that also is either not brittle at all, or if it is, requires...
High technology robots that big companies like Sony strut out are nice, but what I want to know is not how to make a robot as intelligent and motive as a human by brute force, but how to create a simple mobile creature, which can seek out the fuel it runs on, and re-energize itself, and the...
Since that question has been answered and I don't think it's worth making another thread on density; I'll ask here.
Can compounds be denser than their component elements? Could we make something stable that was denser than Osmium? Structure varies density, but perhaps the atoms in elements...
Yes, but on average it is going to be less common for someone to have sex with the gender they aren't attracted to, and if more people with the gay gene aren't reproducing than are, then the population will shrink over time. The number of homosexual people who reproduce in an already small...
Almost all cultures have been patriarchal. Cultures in general tend to have a "sissyphobia", and this could possibly stem from drives in men that would be useful during fathering; encouraging their sons to live up to masculine ideals that are not only useful for attracting women, but in learning...
That's a mouthful, but what I mean is this: why is it that we are concerned about other members of our gender living up to their masculinity or femininity? Also, is this perhaps stronger in males than females?
If a boy or even a man is a "sissy", and exhibits stereotypical feminine traits, he...
Does quantum mechanics also explain Zeno's paradox, in that the smallest instant of time is actually a snapshot of the arrow in two incredibly slightly different places, and the next instant of time collapses the wave function into the new position?
I don't have that much knowledge of quantum...
A larger yield explosion has more energy, and presumably more power. However, is there a point where the power and power density drop of to become constant, and is this also the same with windspeed velocities generated?
Let's say you had an asteroid, which hit the Earth with an energy equal...
I'm not sure what you're getting at. I'm talking about the relative strength of the forces. The electromagnetic force is already 1E+36 times stronger than gravity, but what if it was even stronger?
All I can think of for starters is that molecular bonds would be stronger, so larger structures...
